Illustrated PDF Book

A brave and deeply disturbing account of one man's attempt to confront the visions that haunted him. Clay Steward's gripping journey takes him to a small town in the pacific Northwest where he follows in the tracks of best-selling author Alan Wake and renegade FBI Agent Robert Nightingale. There he travels ever deeper in the woods and ever farther into the heart of darkness to unravel a series of mysterious events that reach hundreds of years into the past and chillingly into the present. The 130-page illustrated PDF Book will be placed in your Alan Wake folder in the Steam Directory:
